[0026] In this application, the word "exemplary" is used to mean "serving as an example, instance, or illustration." Any embodiment described in this application as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. The term "and / or" includes any and all combinations of one or more of the associated listed items.

[0027] The embodiment of the present application provides an air guide plate 100 and an air conditioner.

[0028] like Figure 1 and Figure 2 As shown, the air conditioner provided in the embodiment of the present application includes a casing 200 and an air guide plate 100. The casing 200 is provided with an air outlet 201. The air guide plate 100 is arranged at the air outlet 201. The air guide plate 100 extends along the length direction of the air outlet 201 and can rotate around the length direction of the air outlet 201.

[0029] like Figures 2 to 5 As shown, a ventilation hole 101 is provided on the air guide plate 100, and the ventilation hole 101 has an air inlet end 102 and an air outlet end 103. The end face of the air inlet end 102 is located on the back side of the air guide plate 100, and the end face of the air outlet end 103 is located on the front side of the air guide plate 100, and the aperture of the air outlet end 103 is smaller than the aperture of the air inlet end 102.

[0030] Among them, the air guide plate 100 has a front and a back. The front of the air guide plate 100 is the side of the air guide plate 100 facing the outside of the casing 200, and the back of the air guide plate 100 is the side of the air guide plate 100 facing the inside of the casing 200. The air flow of the air conditioner can flow from the back side of the air guide plate 100 through the ventilation hole 101 to the front side of the air guide plate 100.

[0031] The air guide plate 100 and air conditioner provided in the embodiment of the present application are configured such that a ventilation hole 101 is provided on the air guide plate 100, and the end face of the air inlet end 102 of the ventilation hole 101 is located on the back side of the air guide plate 100, and the end face of the air outlet end 103 of the ventilation hole 101 is located on the front side of the air guide plate 100, and the aperture of the air outlet end 103 is smaller than the aperture of the air inlet end 102. Therefore, when the outlet air flow flows from the air inlet end 102 with a larger aperture to the air outlet end 103 with a smaller aperture, the outlet air flow will be accelerated when passing through the air outlet end 103 (that is, the speed of the outlet air flow will be accelerated). According to the law of conservation of energy, the kinetic energy of the outlet air flow increases, and the thermal energy decreases, so that the temperature of the outlet air flow is reduced, thereby achieving the goal of reducing the outlet air temperature, thereby improving the electric energy utilization rate of the air conditioner and achieving the purpose of energy conservation and emission reduction.

[0032] Specifically, the direction of the air flow blown out by the internal fan of the air conditioner when passing through the ventilation hole 101 is as follows: Figure 6 As shown, assuming that the mass of the outlet airflow is fixed and enters from the air inlet end 102 of the ventilation hole 101, the overall energy is E1, the kinetic energy is Ek1, and the thermal energy is Ep1, and E1=Ek1+Ep1; when the outlet airflow flows out from the air outlet end 103 of the ventilation hole 101, the overall energy is E2, the kinetic energy is Ek2, and the thermal energy is Ep2, and E2=Ek2+EP2; according to the law of conservation of energy, E1=E2, that is, EK1+Ep1=Ek2+Ep2. Figure 6 It can be seen that after the outlet air flow enters from the air inlet end 102 of the ventilation hole 101, the outlet air flow is structurally compressed and then flows out from the air outlet end 103. The gas velocity at the air outlet end 103 increases, and the kinetic energy of an object is proportional to the square of the velocity, so the kinetic energy of the air outlet end 103 is greater than the kinetic energy of the air inlet end 102, that is, Ek2>Ek1, and E1=E2, so the thermal energy Ep2 of the air outlet end 103 is less than the thermal energy Ep1 of the air inlet end 102, so that the outlet temperature of the air outlet end 103 is lower than the outlet temperature of the air inlet end 102, thereby achieving the effect of lowering the outlet temperature.

[0033] In some embodiments of the present application, Figure 5 and Figure 6 As shown, the air deflector 100 includes an air deflector body 110 and an air outlet portion 120 protruding from the front of the air deflector body 110. The ventilation holes 101 penetrate the air deflector body 110 and the air outlet portion 120. The end surface of the air inlet end 102 is located on the air deflector body 110, and the end surface of the air outlet end 103 is located on the air outlet portion 120. By providing the protruding air outlet portion 120 on the front of the air deflector body 110 and having the ventilation holes 101 penetrate the air deflector body 110 and the air outlet portion 120, the distance of the outlet air flow through the ventilation holes 101 can be increased, thereby achieving an enhanced effect of reducing the outlet air temperature.

[0034] Optionally, the air guide plate body 110 and the air outlet portion 120 are an integrally formed structure, thereby reducing processing difficulty and improving production efficiency.

[0035] Alternatively, in some other embodiments of the present application, the air deflector 100 includes an air deflector body 110, the ventilation holes 101 penetrate the air deflector body 110, the end surface of the air inlet end 102 is located on the back of the air deflector body 110, and the end surface of the air outlet end 103 is located on the front of the air deflector body 110. In other words, the air outlet portion 120 is not provided on the air deflector body 110, and the ventilation holes 101 are directly formed on the air deflector body 110, which can also achieve the effect of reducing the outlet air temperature.

[0036] In some embodiments of the present application, the aperture of the ventilation hole 101 may gradually decrease in the direction from the air inlet end 102 to the air outlet end 103 , that is, the ventilation hole 101 may be tapered in the direction from the air inlet end 102 to the air outlet end 103 .

[0037] Alternatively, in other embodiments of the present application, Figure 5 As shown, the ventilation hole 101 may also include a first straight segment 104, a transition segment 105, and a second straight segment 106. The aperture of the first straight segment 104 is larger than the aperture of the second straight segment 106. The transition segment 105 gradually tapers from the air inlet end 102 to the air outlet end 103 (i.e., the aperture of the transition segment 105 gradually decreases from the air inlet end 102 to the air outlet end 103). The large-diameter end of the transition segment 105 is connected to the first straight segment 104, and the small-diameter end of the transition segment 105 is connected to the second straight segment 106. The aperture of the first straight segment 104 remains consistent from the air inlet end 102 to the air outlet end 103, and the aperture of the second straight segment 106 also remains consistent from the air inlet end 102 to the air outlet end 103.

[0038] Optionally, the aperture of the large diameter end of the transition section 105 is the same as the aperture of the first straight section 104, and the aperture of the small diameter end of the transition section 105 is the same as the aperture of the second straight section 106, so that there is a smooth transition between the first straight section 104 and the transition section 105, and there is also a smooth transition between the transition section 105 and the second straight section 106, thereby reducing the resistance of the outlet airflow when flowing in the ventilation hole 101 (i.e., reducing the wind resistance) and increasing the air output.

[0039] Optionally, the aperture of first straight segment 104 is C, the aperture of second straight segment 106 is T, the length of first straight segment 104 is S, and the length of second straight segment 106 is B, where T < C, 0 ≤ B ≤ T, and 0 ≤ S ≤ T. By adjusting the length S of first straight segment 104 and the length B of second straight segment 106 within the above range, a better effect of reducing the outlet air temperature can be achieved. The length of first straight segment 104 refers to the minimum length of first straight segment 104 along the axis of ventilation hole 101; the length of second straight segment 106 refers to the minimum length of second straight segment 106 along the axis of ventilation hole 101.

[0040] Optional, such as Figures 1 to 4 As shown, the air deflector 100 is provided with a plurality of ventilation holes 101, which are distributed in an array on the air deflector 100 to ensure a cooling effect and uniform air discharge. Accordingly, when the air deflector 100 includes an air deflector body 110 and an air outlet 120, the air outlets 120 are distributed in an array on the air deflector body 110, and the plurality of ventilation holes 101 are provided in a one-to-one correspondence with the plurality of air outlets 120.

[0041] Optionally, the inner wall of the vent 101 smoothly transitions from the air inlet end 102 to the air outlet end 103, thereby reducing resistance to the airflow flowing through the vent 101 (i.e., reducing wind resistance) and increasing the air output. Specifically, when the vent 101 includes a first straight segment 104, a transition segment 105, and a second straight segment 106, the first straight segment 104, the transition segment 105, and the second straight segment 106 are smoothly connected in sequence, thereby ensuring a smooth transition between the inner wall of the vent 101 and the air outlet end 103.

[0042] It should be noted that the ventilation holes 101 can be holes extending along the thickness direction of the air deflector 100, or holes that form a certain angle with the thickness direction of the air deflector 100. In other words, the axis of the ventilation holes 101 can be parallel to the thickness direction of the air deflector 100, or form a certain angle with the thickness direction of the air deflector 100. In addition, this application does not impose any particular restrictions on the shape of the ventilation holes 101. For example, the ventilation holes 101 can be circular, square, elongated, or oval.

[0043] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
